SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 313,638, dated March l0, 1885.

Application ined November 24, 18er. (No model.)

To all whom it may concern:

Be it known thatI, NnLsE WILSON, a citizen of the United States, residing at Hutto, in the county of Williamson and State of TeX- as, have invented certain new and useful Improvements in SashFasteners; and I do de.- clare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The objectof this improvement is a sashfastener that will lock the window-sash in po sition when down, and that can also be applied to holding the sash `at different elevations when the window is opened. rIhese results are attained by the mechanism illustrated in the drawings, herewith filed as part hereof, in which the same letters of reference denote the same parts in the difterentviews.

Figure l represents a sectional view of a wi ndow provided with my improvement. Fig. 2 is a front elevation of my improvement detached. Fig. 3 is a section of the same, taken on the line x x of Fig. 2. Fig. 4 represents minor features of the mechanism detached.

A A is the window-frame. B B is the inside sash. C C is the outside sash. D is the outside weather-strip. E is the inside strip. F is the intermediate strip; and b o represent glass panes in the inner and outer sashes secured in position in the usual manner by means of putty, referred to by the letters b c.

G is the sash-fastener, made of metal, and set into a correspondinglyformed recess in the edge of the weather-strip E, as shown in Fig. l, and to which it is secured by screws g g. The front of the sash-fastener is provided with a groove, h, and recess h', for the reception of a spring, H, securedin position by the screw g, which is used to affix the fastener to vthe strip E. The fastener :may also be applied to intermediate strip, F. The upper end of the fastener G is recessed, as shown at G', for the reception of a latch, G2 g2, supported by a pivot, t.

I is a plate having a flange, I', and secured at its lower part to the pivot t', and connected at its upper part with the latch G2 r/'Z by means of a transverse pin, i2, which projects into and moves in slots g in each side of the upper end of the fastener, which is provided at its back part with a circular recess, g4, provided with a square-headed screw, g5, for the purpose of governing the tension of thespringH by causing its inner end to bear more or less forcibly against the same.

' Bl is a plate provided with a screwsocket and prong, b3, and secured within a recess in the side of the sash in a position corresponding to the latch G2 g of the fastener G. Zhen the sash is down, the latch G2 is moved out by means of the operator I I, to bring the latch projection g2 over the plate B2, substan tially as shown in Fig. l, for which purpose the side of the sash is provided with a suitable recess. Vhen the latch is moved, as stated, the sash will be locked in position. The spring I'I is to have sufficient tension to support the weight of the sash in any position, and should the spring become so much worn that its tension cannot be controlled by the setscrew g5 it may be replaced by a new one.

Having explained the construction and operation of my improvement, what I claim as new, and desire to secure by Letters Patent, 1s-

In a sash-fastener, the combination of plate G, recessed as described, and provided with aset-screw, g5, the spring H, and latch G2, hav ing an outer plate, I, provided with rectangular extension I', all constructed and arranged to operate as specified, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NELSE IVILSON.
